Comes with one-size microfiber insert

It's adjustable in both size and absorbency. Adjust the size as your baby grows. Stuff it with as little or as much absorbency as you need to get you through a quick trip to the store, a long car ride, or maybe even overnight.
The outer cover is made from a super soft waterproof laminated polyester knit fabric that features trendy prints and color combinations. The inner layer is made from a top grade microfleece, the fleece inner dries quickly and acts as a stay dry layer next to babies skin. These layers form a pocket into which an absorbent insert is placed. The diaper comes with an extremely absorbant onesize insert made from both hemp and microterry, which will last from birth to potty just like the diaper. Nothing else is needed!
These diapers have a neat cut to give a trim fit. They fasten at the front with a "hook and loop" closure (like Velcro) for quick and easy fastening. There are strong laundry tabs to prevent the fastening sticking to other laundry in the wash.

Sizing
Blueberry diapers adjust simply with snaps to fit most babies from birth to potty training (approx 8 - 35lb+). The nappy has two rows of snaps for adjusting the size as your baby grows.

Summary information
Guaranteed to attract attention to baby's cloth bottom! You will fall in live with them as soon as you get your hands on them! Quick drying, neat fit. Soft fleece inner that doesn't stain. Fleece retains solids well to reduce the chances of leaks. Being one-size this is all you will need to get you through to potty training.
What else will I need? No liners or waterproof covers are needed with these diapers although you can use flushable liners if you wish. You may wish to use a slimmer insert on a new born and a perfect solution to this is the Bum Genius diaper doubler which comes in packs of three.
